Dual-band eight-port MIMO terminal antenna based on radiator multiplexing technology

Abstract

The invention discloses a dual-band eight-port MIMO terminal antenna based on a radiator multiplexing technology. The dual-band eight-port MIMO terminal antenna comprises a dielectric substrate and a pair of dielectric plates perpendicular to the dielectric substrate. A metal floor is arranged on the lower surface of the dielectric substrate, a plurality of antenna pair units are arranged on the dielectric substrate, each antenna pair unit comprises a first antenna unit on the inner side wall of the dielectric substrate and a second antenna unit on the outer side wall of the dielectric substrate, each antenna pair unit comprises two antenna ports, and one antenna port is a first feeding point on the metal floor; the other antenna port is a second feeding point of the second antenna unit; and the first antenna unit is connected with a first feeding point for feeding through a feeder line and a coaxial inner core penetrating through a floor, and the second antenna unit directly feeds through a coaxial line. The antenna has the advantages that the antenna multiplexes the unit radiator, an extra decoupling structure is not needed, dual-band work is achieved, and the isolation degree between the antenna units is high, and is suitable for a 5G intelligent terminal.
